Hematopoietic stem-cell transplantation for the treatment of severe combined immunodeficiency. (1/1678)

BACKGROUND: Since 1968 it has been known that bone marrow transplantation can ameliorate severe combined immunodeficiency, but data on the long-term efficacy of this treatment are limited. We prospectively studied immunologic function in 89 consecutive infants with severe combined immunodeficiency who received hematopoietic stem-cell transplants at Duke University Medical Center between May 1982 and September 1998. METHODS: Serum immunoglobulin levels and lymphocyte phenotypes and function were assessed and genetic analyses performed according to standard methods. Bone marrow was depleted of T cells by agglutination with soybean lectin and by sheep-erythrocyte rosetting before transplantation. RESULTS: Seventy-seven of the infants received T-cell-depleted, HLA-haploidentical parental marrow, and 12 received HLA-identical marrow from a related donor; 3 of the recipients of haploidentical marrow also received placental-blood transplants from unrelated donors. Except for two patients who received placental blood, none of the recipients received chemotherapy before transplantation or prophylaxis against graft-versus-host disease. Of the 89 infants, 72 (81 percent) were still alive 3 months to 16.5 years after transplantation, including all of the 12 who received HLA-identical marrow, 60 of the 77 (78 percent) who were given haploidentical marrow, and 2 of the 3 (67 percent) who received both haploidentical marrow and placental blood. T-cell function became normal within two weeks after transplantation in the patients who received unfractionated HLA-identical marrow but usually not until three to four months after transplantation in those who received T-cell-depleted marrow. At the time of the most recent evaluation, all but 4 of the 72 survivors had normal T-cell function, and all the T cells in their blood were of donor origin. B-cell function remained abnormal in many of the recipients of haploidentical marrow. In 26 children (5 recipients of HLA-identical marrow and 21 recipients of haploidentical marrow) between 2 percent and 100 percent of B cells were of donor origin. Forty-five of the 72 children were receiving intravenous immune globulin. CONCLUSIONS: Transplantation of marrow from a related donor is a life-saving and life-sustaining treatment for patients with any type of severe combined immunodeficiency, even when there is no HLA-identical donor.  (+info)

Familial antiphospholipid antibody syndrome: criteria for disease and evidence for autosomal dominant inheritance. (2/1678)

OBJECTIVE: To develop diagnostic criteria for a familial form of antiphospholipid antibody syndrome (APS), identify families with >1 affected member, examine possible modes of inheritance, and determine linkage to potential candidate genes. METHODS: Family members of probands with primary APS were analyzed for clinical and laboratory abnormalities associated with APS. Families with > or =2 affected members were analyzed by segregation analysis and typed for candidate genetic markers. RESULTS: Seven families were identified. Thirty of 101 family members met diagnostic criteria for APS. Segregation studies rejected both environmental and autosomal recessive models, and the data were best fit by either a dominant or codominant model. Linkage analysis showed independent segregation of APS and several candidate genes. CONCLUSION: Clinical and laboratory criteria are essential to identify the spectrum of disease associated with APS. We believe a set of criteria was developed that can precisely define affected family members with APS. Modeling studies utilizing these criteria strongly support a genetic basis for disease in families with APS and suggest that a susceptibility gene is inherited in an autosomal dominant pattern. However, in these families, APS was not linked with HLA, Fas, or other candidate genes, including beta2-glycoprotein 1, HLA, T cell receptor beta chain, Ig heavy chain, antithrombin III, Fas ligand, factor V, complement factor H, IgK, and Fas.  (+info)

Natural variation of the expression of HLA and endogenous antigen modulates CTL recognition in an in vitro melanoma model. (3/1678)

Increasing attention has been devoted to elucidating the mechanism of lost or decreased expression of MHC or melanoma-associated antigens (MAAs), which may lead to tumor escape from immune recognition. Loss of expression of HLA class I or MAA has, as an undisputed consequence, loss of recognition by HLA class I-restricted cytotoxic T cells (CTLs). However, the relevance of down-regulation remains in question in terms of frequency of occurrence. Moreover the functional significance of epitope down-regulation, defining the relationship between MHC/epitope density and CTL interactions, is a matter of controversy, particularly with regard to whether the noted variability of expression of MHC/epitope occurs within a range likely to affect target recognition by CTLs. In this study, bulk metastatic melanoma cell lines originated from 25 HLA-A*0201 patients were analyzed for expression of HLA-A2 and MAAs. HLA-A2 expression was heterogeneous and correlated with lysis by CTLs. Sensitivity to lysis was also independently affected by the amount of ligand available for binding at concentrations of 0.001 to 1 mM. Natural expression of MAA was variable, independent from the expression of HLA-A*0201, and a significant co-factor determining recognition of melanoma targets. Thus, the naturally occurring variation in the expression of MAA and/or HLA documented by our in vitro results modulates recognition of melanoma targets and may (i) partially explain CTL-target interactions in vitro and (ii) elucidate potential mechanisms for progressive escape of tumor cells from immune recognition in vivo.  (+info)

Insulin dependent diabetes mellitus (IDDM) and autoimmune thyroiditis in a boy with a ring chromosome 18: additional evidence of autoimmunity or IDDM gene(s) on chromosome 18. (4/1678)

A 4 year 3 month old boy with insulin dependent diabetes mellitus (IDDM), autoimmune thyroiditis, slight mental retardation, facial dysmorphism, and a de novo ring chromosome 18 (deletion 18q22.3-18qter) is described. This unique association of defects could represent a chance association. Alternatively, the clinical features could be the result of the chromosomal aberration. If so, one could speculate that a gene or genes on chromosome 18 might act as a suppressor or activator of the autoimmune process by itself or in concert with other IDDM loci.  (+info)

The predisposition to type 1 diabetes linked to the human leukocyte antigen complex includes at least one non-class II gene. (5/1678)

The human leukocyte antigen (HLA) complex, encompassing 3.5 Mb of DNA from the centromeric HLA-DPB2 locus to the telomeric HLA-F locus on chromosome 6p21, encodes a major part of the genetic predisposition to develop type 1 diabetes, designated "IDDM1." A primary role for allelic variation of the class II HLA-DRB1, HLA-DQA1, and HLA-DQB1 loci has been established. However, studies of animals and humans have indicated that other, unmapped, major histocompatibility complex (MHC)-linked genes are participating in IDDM1. The strong linkage disequilibrium between genes in this complex makes mapping a difficult task. In the present paper, we report on the approach we have devised to circumvent the confounding effects of disequilibrium between class II alleles and alleles at other MHC loci. We have scanned 12 Mb of the MHC and flanking chromosome regions with microsatellite polymorphisms and analyzed the transmission of these marker alleles to diabetic probands from parents who were homozygous for the alleles of the HLA-DRB1, HLA-DQA1, and HLA-DQB1 genes. Our analysis, using three independent family sets, suggests the presence of an additional type I diabetes gene (or genes). This approach is useful for the analysis of other loci linked to common diseases, to verify if a candidate polymorphism can explain all of the association of a region or if the association is due to two or more loci in linkage disequilibrium with each other.  (+info)

Genetic determination of islet cell autoimmunity in monozygotic twin, dizygotic twin, and non-twin siblings of patients with type 1 diabetes: prospective twin study. (6/1678)

OBJECTIVE: To test the hypothesis that non-diabetic dizygotic and monozygotic twin siblings of patients with type 1 diabetes have a similar high prevalence of islet cell autoantibodies, thus suggesting that islet cell autoimmunity is mainly environmentally determined. DESIGN: Prospective twin study. SETTING: Two specialist centres for diabetes in the United States. PARTICIPANTS: Non-diabetic monozygotic twin (n=53), dizygotic twin (n=30), and non-twin (n=149) siblings of patients with type 1 diabetes; 101 controls. MAIN OUTCOME MEASURES: Analysis of progression to diabetes and expression of anti-islet autoantibodies. RESULTS: Monozygotic twin siblings had a higher risk of progression to diabetes (12/53) than dizygotic twin siblings (0/30; P<0.005). At the last follow up 22 (41.5%) monozygotic twin siblings expressed autoantibodies compared with 6 (20%) dizygotic twin siblings (P<0.05), 16 (10.7%) non-twin siblings (P<0.0001), and 6 (5.9%) controls (P<0.0001). Monozygotic twin siblings expressed multiple (>/=2) antibodies more often than dizygotic twin siblings (10/38 v 1/23; P<0.05). By life table analysis the probability of developing positive autoantibodies was higher among the monozygotic twin siblings bearing the diabetes associated HLA DQ8/DQ2 genotype than in those without this genotype (64.2% (95% confidence interval 32.5% to 96%) v 23.5% (7% to 40%) at 10 years of discordance; P<0.05). CONCLUSION: Monozygotic and dizygotic twins differ in progression to diabetes and expression of islet cell autoantibodies. Dizygotic twin siblings are similar to non-twin siblings. These two observations suggest that genetic factors play an important part in determination of islet cell autoimmunity, thus rejecting the hypothesis. In addition, there is a high penetrance of islet cell autoimmunity in DQ8/DQ2 monozygotic twin siblings.  (+info)

Linkage of Crohn's disease to the major histocompatibility complex region is detected by multiple non-parametric analyses. (7/1678)

BACKGROUND: There is evidence for genetic susceptibility to Crohn's disease, and a tentative association with tumour necrosis factor (TNF) and HLA class II alleles. AIMS: To examine the potential of genetic linkage between Crohn's disease and the MHC region on chromosome 6p. METHODS: TNF microsatellite markers and, for some families, additional HLA antigens were typed for 323 individuals from 49 Crohn's disease multiplex families to generate informative haplotypes. Non-parametric linkage analysis methods, including sib pair and affected relative pair methods, were used. RESULTS: Increased sharing of haplotypes was observed in affected sib pairs: 92% (48/52) shared one or two haplotypes versus an expected 75% if linkage did not exist (p=0.004). After other affected relative pairs were included, the significance level reached 0.001. The mean proportion of haplotype sharing was increased for both concordant affected (pi=0.60, p=0.002) and unaffected sib pairs (pi=0.58, p=0. 031) compared with the expected value (pi=0.5). In contrast, sharing in discordant sib pairs was significantly decreased (pi=0.42, p=0. 007). Linear regression analysis using all three types of sib pairs yielded a slope of -0.38 at p=0.00003. It seemed that the HLA effect was stronger in non-Jewish families than in Jewish families. CONCLUSIONS: All available analytical methods support linkage of Crohn's disease to the MHC region in these Crohn's disease families. This region is estimated to contribute approximately 10-33% of the total genetic risk to Crohn's disease.  (+info)

Auto- and alloimmune reactivity to human islet allografts transplanted into type 1 diabetic patients. (8/1678)

Allogeneic islet transplantation can restore an insulin-independent state in C-peptide-negative type 1 diabetic patients. We recently reported three cases of surviving islet allografts that were implanted in type 1 diabetic patients under maintenance immune suppression for a previous kidney graft. The present study compares islet graft-specific cellular auto- and alloreactivity in peripheral blood from those three recipients and from four patients with failing islet allografts measured over a period of 6 months after portal islet implantation. The three cases that remained C-peptide-positive for >1 year exhibited no signs of alloreactivity, and their autoreactivity to islet autoantigens was only marginally increased. In contrast, rapid failure (<3 weeks) in three other cases was accompanied by increases in precursor frequencies of graft-specific alloreactive T-cells; in one of them, the alloreactivity was preceded by a sharply increased autoreactivity to several islet autoantigens. One recipient had a delayed loss of islet graft function (33 weeks); he did not exhibit signs of graft-specific alloimmunity, but developed a delayed increase in autoreactivity. The parallel between metabolic outcome of human beta-cell allografts and cellular auto- and alloreactivity in peripheral blood suggests a causal relationship. The present study therefore demonstrates that T-cell reactivities in peripheral blood can be used to monitor immune mechanisms, which influence survival of beta-cell allografts in diabetic patients.  (+info)

BACKGROUND: The anti-HLA antibody can be detected using either a complement-dependent lymphocytotoxicity (CDC) assay or a flow cytometry crossmatch (FCXM) in renal transplantation. Discordant results are often obtained because the two methods detect different reaction phases between the donor lymphocytes and the recipient sera. This study was intended to confirm that antibody binding and cytotoxicity to the lymphocytes can be detected simultaneously in a single FCXM assay, cytotoxic FCXM.. METHODS: In the cytotoxic FCXM, the antibody binding to the lymphocytes was measured using anti-IgG-FITC, and the cytotoxicity using 7-aminoactinomycin D (7-AAD) after adding complement. For an evaluation of two test parameters, the cytotoxicity test moiety (dead-cell percentage) was compared with the anti-human globulin (AHG)-CDC, and the antibody-binding test moiety (sample/control fluorescence ratio) with the conventional FCXM in 77 positive and 30 negative crossmatches.. RESULTS: In the cytotoxic FCXM, ...

Background-The effect of donor-recipient human leukocyte antigen (HLA) matching on outcomes remains relatively unexplored in pediatric patients. The objective of this study was to investigate the effects of donor-recipient HLA matching on graft survival in pediatric heart transplantation. Methods and Results-The UNOS database was queried for heart transplants occurring between October 31, 1987 to December 31, 2012 in a recipient aged ≤ 17 with at least one postoperative follow-up visit. Retransplants were excluded. Transplants were divided into 3 donor-recipient matching groups: no HLA matches (HLA-no), 1 or 2 HLA matches (HLA-low), and 3-6 HLA matches (HLA-high). Primary outcome was graft loss. 4471 heart transplants met study inclusion criteria. High degree of donor-recipient HLA matching occurred infrequently; (HLA-high n=269 (6 %) v. HLA-low n=2683 (60%) v. HLA-no n=1495 (34%). There were no differences between HLA matching groups in frequency of coronary vasculopathy (p=0.19) or rejection ...
Methods and Results-The UNOS (United Network for Organ Sharing) database was queried for heart transplants occurring between October 31, 1987, and December 31, 2012, in a recipient aged ≤17 years with ≥1 postoperative follow-up visit. Retransplants were excluded. Transplants were divided into 3 donor-recipient matching groups: no HLA matches (HLA-no), 1 or 2 HLA matches (HLA-low), and 3 to 6 HLA matches (HLA-high). Primary outcome was graft loss. Four thousand four hundred seventy-one heart transplants met the study inclusion criteria. High degree of donor-recipient HLA matching occurred infrequently: HLA-high (n=269; 6%) versus HLA-low (n=2683; 60%) versus HLA-no (n=1495; 34%). There were no differences between HLA matching groups in the frequency of coronary vasculopathy (P=0.19) or rejection in the first post-transplant year (P=0.76). Improved graft survival was associated with a greater degree of HLA donor-recipient matching: HLA-high median survival, 17.1 (95% confidence interval, ...

The science of PGD has been pushed to the point where it can also identify an embryo that would be the best stem cell donor for its sibling. The application of this science is in its early stages but holds tremendous promise for all children suffering from diseases that can be treated with a stem cell transplant, like leukemia. If we had become pregnant with a healthy genetic match though IVF, then our doctors could have painlessly taken stem cells from the babys umbilical cord at birth to cure his or her older brothers bone marrow failure and save Henrys life. Unfortunately, we were unsuccessful and Henrys deteriorating health forced us to undertake his transplant one year ago using a less desirable unrelated bone marrow donor. Henry is alive today but clinically has suffered so much more - spending a year in and out of the hospital, enduring invasive lung, brain, liver and skin biopsies - than if he had received stem cells from a genetically matched sibling.

The most highly upregulated genes were IFN\inducible genes and IFN neutralisation in MLCs abrogated their induction. The microRNA\155 (miR\155) was also found to be significantly induced in the mismatched setting but its induction was not diminished by blocking IFN.

This years extra mural meeting was opened by Sebastiaan Heidt from the ETRL who discussed the pilot on patient-based external proficiency testing (EPT) cases. First, the paper-based EPT that was sent around in July 2015 was discussed. The results from this exercise showed a striking diversity in the advice on whether the transplant could go ahead or not. Some important issues came up, such as what to do in case a crossmatch without DTT is positive, the crossmatch with DTT is negative, and no information is available on autologous crossmatch results. Furthermore, there was lots of discussion on how to deal with HLA antibodies detected by Luminex only in case of a negative crossmatch. Some practical issues, such as how to deal with the prozone effect in Luminex assays were discussed. It was clear that center-specific policies on the value of antibodies detected by Luminex only are quite different. Next, the patient-based EPT on actual samples used for crossmatching was discussed. Also here, it ...

TREOSULFAN-BASED CONDITIONING REGIMEN IN SIBLING AND ALTERNATIVE DONOR HEMATOPOIETIC STEM CELL TRANSPLANTATION FOR CHILDREN WITH SICKLE CELL DISEASE
BACKGROUND:. In 1986, the Department of the Navy initiated the National Bone Marrow Donor Registry. Because the support of a National Bone Marrow Donor Registry was not very closely related to the Navys primary missions, in 1989 the management of the contract for the program was transferred by the Congress from the Navy to the NHLBI.. By 1989, bone marrow transplantation had become an effective and accepted treatment for an increasing number of diseases of the bone marrow and the immune system. Until only a few years prior to 1989, most marrow donors were siblings, carefully matched for HLA (tissue) antigens. Since only a small proportion of candidates for a bone marrow transplant have matched brothers or sisters, additional family members were tried as donors. These included parents, children, slightly mismatched siblings, and other relatives. Even with the broadening of the bone marrow donor source, no more than 30-40 percent of patients with diseases amenable to marrow transplant therapy had ...
WEDNESDAY, March 27, 2019 (HealthDay News) -- The chances of finding an unrelated bone marrow donor are higher for U.S. patients of European descent than for those of non-European descent, a new study finds.. A bone marrow transplant can sometimes help people with life-threatening blood cancers by replacing the patients cells with healthy ones from a donor. A brother or sister with the same genetic markers as the recipient is the ideal donor.. For patients without a suitable sibling donor, a transplant from a matched unrelated donor is typically the next best option.. In the new study, researchers looked at just over 1,300 blood cancer patients at Memorial Sloan Kettering Cancer Center, in New York City, who sought a fully matched bone marrow donor between 2005 and 2017..

Background: HLA mismatches of the donor and recipient causing de novo donor-specific HLA antibodies (dnDSA) are a risk factor for immunologic complications and poor graft survival. Evaluating histocompatibility based on HLA epitopes may improve outcomes after kidney transplantation and better prevent sensitization than classical matching of HLA class I and II antigens. To date there is very few data examining clinical outcomes based on HLA epitope matching.. Patients and methods: 2,787 consecutive adult kidney transplants performed 1995-2015 without preformed DSA have been included. De novo DSA were detected by Luminex single antigen assay. HLAMatchmaker score was calculated as the weighted sum of eplets of high resolution patient and donor typing.. Results: The distribution of the HLA epitope mismatch (assessed by the HLAMatchmaker algorithm) and the correlation to the count of mismatched A,B,C,DR,DQ-HLA molecules is shown in Fig.1a and Fig.1b. Categorization by HLAMatchmaker epitopes ...
Minorities are far less likely to find a compatible bone marrow donor on the national registry than whites. Although National Marrow Donor Program has doubled since 2004 the number of transplants it abets for black patients, still face the longest odds.
Abstract: Many potential kidney transplant recipients are unable to receive a live donor transplant due to crossmatch or blood type incompatibility. Kidney paired donation increases access to live donor transplantation but has been significantly underutilized. We established a kidney paired donation program including consented incompatible donor/recipient pairs as well as compatible pairs with older non-human leukocyte antigen identical donors. Over a 3-year period, a total of 134 paired donor transplants were performed, including 117 incompatible pairs and 17 compatible pairs. All transplants were done with negative flow cytometry crossmatches and five were done with desensitization combined with paired donation. Kidney paired donation transplants included two-way and three-way exchanges as well as three chains initiated by nondirected donors. Of the sensitized recipients transplanted by paired donation, 44% had calculated panel reactive antibody levels greater than 80%. Transplantation of ...

This year, Be the Match will be aided by the Auggie baseball team, including assistant coach Troy Deden 07, a transplant recipient.. Deden [pictured here] was diagnosed with leukemia in 2008, after he had graduated and had joined the Augsburg coaching staff. He went through treatment for eight months, missing an entire baseball season, and was in remission for nine months following chemotherapy. Then, the leukemia returned.

RESULTS CyA neurotoxicity was seen more frequently in HLA-mismatched and unrelated donor transplants. The frequency of CyA neurotoxicity was 4% for patients with a 5/6 or 6/6 HLA match, 13% for matched unrelated donor transplants, and 50% for haplotypic 3/6 or 4/6 transplants. Patients with matched unrelated donor transplants and haplotypic transplants presented earlier in the posttransplant time course and had decreased survival time relative to patients with HLA-matched transplants. Imaging abnormalities most commonly affected the occipital lobes and the posterior cerebral hemispheres; both cortical and white matter involvement was identifiable as T1 hypointense and T2 hyperintense signal with associated gyral swelling and sulcal effacement on the initial MR studies. Hypodensity in the affected areas was noted on CT scans. Contrast enhancement was seen in HLA-mismatched and unrelated transplants only. Follow-up imaging showed interval decreases in subcortical edema; however, residual signal ...

The three past medical events that may cause a recipient to have antibodies are pregnancy, blood transfusion or prior transplantation. Refinements in laboratory techniques for crossmatching have led to very sensitive and accurate testing that is probably responsible for some of the improved outcomes of kidney transplantation. Although this testing is now highly complex and may involve as many as ten to fifteen different/separate tests, the final result is fairly simple. If the crossmatch is positive, the recipient has responded to the donor (antibodies were present and killed the cells) and transplantation should not be carried out. A negative crossmatch means the recipient has not responded and transplantation may proceed. Although this may seem confusing, we should all think of a crossmatch as the final and very important test indicating a go or no go with a transplant operation. A positive crossmatch essentially says the recipient will reject the donor organ and the transplant should not be ...

We investigated the impact of occurrence of GVHD on transplantation outcomes in a large cohort of AML pts given allogeneic PBSC after RIC conditioning. Data from 1859 AML pts in fi rst (n=1439) or second (n=420) CR transplanted between 2000 and 2009 following a RIC regimen at EBMT affi liated centres were analyzed. Pts were given PBSC from HLA-identical sibling (MRD, n=1208), or from HLA-matched unrelated donors (MUD, n=651). ATG was given in 269 (22%) MRD and in 267 (41%) MUD recipients, respectively, while 151 (13%) MRD and 165 (25%) MUD recipients received in-vivo T cell depletion with alemtuzumab. The impact of chronic GVHD (cGVHD) on outcomes was assessed using time-dependent multivariate Cox models and in a landmark analysis at 18 months after transplant. ...
Once the indication to transplant has been confirmed, patients and their relatives must be informed on how the transplant is performed. Patients should understand that identifying a stem cell donor is an absolute prerequisite to perform a transplant. Accordingly, patients should be informed about the human leukocyte antigen (HLA) genetic system, its specificity for each individual, how it is inherited by parents according to the Mendelian laws, and what is the probability to find a compatible donor in the family group. Understanding the HLA system is crucial to explain why the use of a HLA family-matched sibling donors is considered standard and when such a sibling is not available; an international search has to be performed to identify a HLA-compatible unrelated donor. It is important to underline that more than 30 million of potentially available donors are registered by the World Marrow Donor Association (WMDA), and the probability to find a compatible donor is between 50 and 80% according ...

Allogeneic stem cell transplantation, though often curative, is associated with high nonrelapse mortality and long-term morbidity, particularly when cells from unrelated donors are used. Many physicians and patients opt for a trial of interferon-α (IFN)-based therapy first, reserving transplantation for patients with inadequate response or intolerance to IFN. Data were ...
Nurses pricked his finger to get an extra drop of blood to test his compatibility with people who needed bone marrow transplants. Six months later, because antigens in their blood matched, he was asked to donate bone marrow to a Utah teen near death from leukemia. In 2003, he began recruiting bone marrow donors at Houston post offices for the National Marrow Donor Program. The donor registry allows patients and their physicians access to 10 million potential bone marrow donors worldwide. [...] donations are crucial to help those with blood and immune system diseases, such as leukemia and lymphoma.

K.. AU - Kao, R. H.. AU - Lin, C. L.. AU - Lin, P. Y.. PY - 2012/12/1. Y1 - 2012/12/1. N2 - We detected a rare HLA-A*24:137 allele in an unrelated Taiwanese haematopoietic stem cell donor during a routine SBT (sequence-based typing) HLA typing exercise. The DNA sequence of A*24:137 is identical to the sequence of A*24:02:01:01 in exons 2 and 3 except at codon 21 where CGC was replaced with CAA. The DNA variation caused an amino acid alteration at amino acid residue 21 (R-,Q). The HLA haplotype in association with A*24:137 may be deduced as A*24:137-B*15-DRB1*14. The formation of A*24:137 was probably the result of a nucleotide point mutation involving A*24:02:01:01. It remains to be determined whether A*24:137 is restricted to Taiwanese/Chinese ethnicity..

SEATTLE - Study demonstrates that marrow transplantation using HLA-matched unrelated donors can be safe and effective therapy for patients with chronic myeloid leukemia (CML) in chronic phase. Seattle researchers also believe that transplantation should not be limited to younger people, under the age of 40 years. Fred Hutchinson Cancer Research Center researchers published the results of their study in the April 2, 1998, issue of The New England Journal of Medicine.. Transplantation has been shown to be the cure for many blood disorders and inherited diseases, including CML. One obstacle has always been the identification of a suitably matched donor. Previously, it was believed that only those CML patients with an HLA-matched sibling donor had an option for curative treatment. This study concludes that marrow transplantation from an HLA-matched unrelated donor can be the treatment of choice for many CML patients and should be considered early in the course of disease to optimize ...

SAN FRANCISCO -- A father who believes a lack of bone marrow donors contributed to his sons death from leukemia says a federal court ruling allowing most bone marrow donors to be paid will save lives
Over 70 % of patients who need a stem cell or bone marrow transplant cannot find a match in their family and require an unrelated donor to proceed with treatment.[1] These donors are recruited at stem cell drives where individuals are invited to swab their cheeks and to sign a consent form to register as potential stem cell donors.[2] A growing body of literature highlights the need for ethnically-diverse stem cell donors.[3-9] Patients in need of a stem cell transplant are more likely to find a genetically-matched donor from their own ethnic group. This is due to the association between individuals genetic heritage and their Human Leukocyte Antigen (HLA) alleles, which are used to match patients to donors. Minority status is often associated with less-common HLA types, underscoring the importance of building ethnic diversity into the worlds stem cell and marrow donor registries.[10] Some registries, including the U.S. National Marrow Donor Program (NMDP)s Be The Match registry, have ...
Global leader in bone marrow transplantation. We conduct research to improve transplant outcomes provide support and resources for patients.
Subjects will be hospitalized and undergo high doses of chemotherapy which will destroy the childs normal cells including their bone marrow (which forms blood cells) in order to prepare their body for the umbilical cord blood transplant. The cord blood transplant is intended to rescue your childs bone marrow from the bad effects of the procedure. The child will receive 80% of a standard cord blood transplant followed by 20% supplemental stem cell called ALD-101.. The study will evaluate if these cells (ALD-101) will repopulate the bone marrow more rapidly after transplant. This would shorten the period of time that the transplanted subject would be at risk for infection and bleeding and would also decrease the number of red blood cell and platelet transfusions needed.. ALD-101 has been used as a supplement to cord blood transplant in twenty-eight children with genetic diseases and malignancy in one previous clinical study that is on-going.. The main purpose of this research study is to test ...

Most of the time, another person s blood stem cells must serve as the donor cells. Donors must be matched through a system called human leukocyte antigens (HLA). This system identifies proteins on the surface of our cells which code for our unique identity. Each of us has six important proteins -- three inherited from our mother and three from our father. In a typical family, each parent will match halfway and each sibling will have a 25 percent chance of matching the patient. Since a full match is best, many patients don t have a close enough match in their family. The National Marrow Donor Program (NMDP) was established 20 years ago to allow adults to donate their blood stem cells to a patient in need of a bone marrow donor. Currently there are over seven million adults who have volunteered to participate in the NMDP registry. The NMDP has facilitated over 20,000 transplants in the past 17 years. Even with the NMDP, roughly half of the patients in need of a bone marrow transplant cannot find a ...

Siblings who donate bone marrow to their brothers or sisters are more adaptive at school, their teachers tell researchers, but the children themselves arent so sure. These same sibling-donors report more anxiety and lower self-esteem than do non-donor siblings of transplant patients.
Since its inception, Jeffersons BMT Program has completed more than 1,000 bone marrow transplants, with increasingly impressive outcomes. These include the regions highest actual one-year patient survival rates, according to National Marrow Donor Program Center Specific analyses for 2013 and 2014. The transplant program now has an international reputation for its unique approach to haplo-identical transplants. Drs. Flomenberg, Grosso, Carabasi, Wagner, and Filicko-OHara all play important roles in the transplant effort. Dr. Neal Flomenberg continues to lead this program and remains an active clinical participant in all programmatic activities.. In an October 2014 article published in the Biology of Blood and Marrow Transplantation, Jefferson reported disease-free and overall survival at 2 years are 74% and 77%, respectively, consistent with the findings (of previous work) and supporting the use of this approach in earlier stage patients lacking a matched related donor..

Hi, everyone! By way of background, Im a 31-year-old male and was diagnosed about two months ago with AML. I achieved remission after my second round of chemotherapy and am now gearing up for a transplant. I have a younger sibling who is a half-match and am told that I dont have any suitable unrelated matches.. Ive sought opinions from two different hospitals: one is recommending using my sibling as the donor (haploidentical transplant), while the other wants to use unrelated cord blood. Does anyone have experience with either method (or been in a situation where theyve had to make a decision like this) and have any advice? Thank you so much in advance for your help!. ...

The NMDP (National Marrow Donor Program) is not able to break down the likelihood of finding a match for patients of mixed heritage. However, the challenge for finding a match is probably greatest in this growing community of racially and ethnically diverse people because the tissue type is very complex. The chance that two people from two different groups will create a new tissue type in children is very high. This is why there is such a great need for donors from all backgrounds to join the Be The Match Registry - to increase the likelihood that all patients will find a match ...

Alternative Donor Transplantation: Results of Parallel Phase II Trials using HLA-Mismatched Related Bone Marrow or Unrelated Umbilical Cord Blood Grafts
line. Our number one priority is to protect our donors, potential donors and patients while continuing to offer a second chance of life to those who need it. Patients with blood disorders, such as leukaemia and thalassemia around the world are still in urgent need of blood stem cell transplants. That doesnt change. The fewer donors we have, the lesser the chance of finding a match. As it is, the chance of finding a successful match is approximately one in 100 000.. Only 30% of people are lucky enough to find donors in their family, while the remaining 70% must look elsewhere for a match. When local matches arent found, international registries are accessed, but even so, the odds of finding a match are slim, and in the event of an international match being found, the process is an expensive one.. In SA, the registry is currently not reflective of our demographics and unfortunately worldwide only 27% of donors are of colour, which makes finding a match even more problematic, she ...
